POWERED BY YOU

The MATRIX PowerWatch is the world’s first smartwatch that you never have to charge.
Powered by your body heat, it measures calories burned, activity level, and sleep using our advanced thermoelectric technology.
It is the only smartwatch to feature a power meter which displays how much electrical power you are generating.

FEATURES

Never
have to recharge

The PowerWatch runs off your body heat and when you take it off, your data is stored in memory and it goes to sleep; put it back on and the watch turns back on right where you left it. It's got a power meter that tells you how much electricity your body heat is producing.

AccurateCalorie Count

Your body turns the calories you consume into heat. The PowerWatch accurately measures the calories you burn using our advanced thermoelectric technology.

Step Counter

Track the number of steps you take to make sure you’re staying active.

Sleep Tracker

Monitor your sleep quality and never worry about having to charge the PowerWatch in the morning.

Water Resistant
to 50M

With groundbreaking water resistant capabilities, The PowerWatch has the highest waterproof rating of any smartwatch on the market.

Customized by you

With a range of fully customizable options, it's easy to make The PowerWatch yours. Change the watch face to suit your mood.

PowerWatch App

The app will show you how many calories you've burned, steps you've taken, and whether you're getting a good night's rest. It will even show you how much electric power you've produced during the day, just like your electric meter at home! Share this data with your friends and setup competitions to see who can burn the most calories or generate the most power.

FAQ's

How does the PowerWatch accurately measure calories burned?

A calorie is defined as the amount of heat energy required to raise 1 gram of water by 1 degree Celsius. Scientists measure calories burned by the human body by measuring the amount of heat the body produces. This is the most accurate way of measuring calorie loss. The PowerWatch's thermoelectric technology measures calories burned in a similar fashion by measuring the amount of heat you produce.

What happens when I take off the PowerWatch?

The PowerWatch goes to sleep and runs off battery power where it draws a tiny amount of current. Put it back on and it turns on with the correct time.

How come I've never heard of thermoelectrics before?

Thermoelectric technology has been around for decades, but only in limited niche applications like NASA built spacecraft. With the recent advent of low-power electronics, we felt it was the right time to use our thermoelectric technology for a consumer product.
